Seriously though, do you have a performance tuner? Which one? Superchips is probably the best one on the market for WJs and a LOT of people who have it, would not buy it again. The gains just arent enough to make it worth the expense.

OT: I love my Superchips. When premium is affordable(currently over $4/g now) I'll run the 91 performance tune and it really wakes it up. But the 87 tune is no slouch either, great for every day driving. I can't say anything positive about mpgs though because it's hard to keep my foot out of it. That's probably the best option under $200. Flyin Ryan makes good tunes but you need an SCT tuner $300+ and then $150-200 for his tunes. Don't quote me though because it's been a while since I looked into his pricing.
